Check out the websites of the major players (Cannon, Epson, HP, Brother, etc) and look for scanners that have "document feeders" or "sheet feeders". You may have better luck looking at All-In-On/Multi Function devices as many of these include document/sheet feeders and some of the better ones seem to do a good job with photographs.

A word of caution, though. Most photographs are printed on thicker paper stock, and are of a small-ish size and not all feeders can handle them. You may have to take a couple of photographs to the store for testing.

Hope this helps,
